Review on Bingfu Dual Band VHF UHF Ham Radio Magnetic Base Antenna – SMA Male for Handheld Two Way Radios by Sarjus Baer

Decent solution for occasional use with a handheld scanner in a car to improve the signal instead of an auxiliary 17" antenna or a standard short antenna. I simply placed the magnet base on the roof, then fed the wire through the door opening and closed the door. Plug the BNC connector into the front seat and connect it to the scanner. Yes, it's a thin wire compared to shielded cables, but that makes it withstand a closed door. Haven't deployed the antenna at freeway speeds so can't comment on wind resistance, but at 40mph it stays in place.
